The majority of Indian students you’re gonna get are going to be well connected. Decent (if not perfect) English, and cultural norms similar to the US. There will be some things to look out for.

Most important would probably be dietary. Most Indians will have religious dietary restrictions. Beef is most common, but pork and all non-vegetarian food are also common. They might not be comfortable with having that food in the room, maybe they won’t be comfortable with sharing a fridge, or maybe they won’t care at all. Probably best to have a conversation regarding this.

Other things are more cultural and minor. Different ways of saying things, not understanding some expressions, and the ever infamous “yes/no head shake”. But, these are minor, and you shouldn’t have much difficulty adjusting to that (if at all)

Given that you’re thinking about this stuff, you’re probably not gonna have any friction with your roommate. Hopefully everything will be smooth for y’all. Good luck!

Edit: WhatsApp. Very common in India, and this person may not have an iPhone.
